On Friday night, EDM sensation Krewella stopped by the new Kumi Japanese Restaurant + Bar by Akira Back at Mandalay Bay for a special preview dinner (Kumi officially opens on Tuesday), where the “Alive” producers got the first taste of chef Akira Back’s exciting new Japanese menu. “They were having a great time and said they loved everything,” says an onlooker.

Member Jahan Yousaf shared a Dragon Bowl with Back before heading off to Light for their set.
